BUMP-BLOCK.

SPECIFICATION forming part of Letters Patent No. 600,428, dated March 8, 1898.

Application filed May 1, 1897. Serial No. 634,727. (No model.)

To aZZ whom it may concern:

Be it known that we, NOBLE \V. LADD, JO- SEPH A. Snoncnnss, and J onN W. SMITI-ISON, of Saginaw, inthe county of Hot Spring and State of Arkansas, have invented certain new and useful Improvements in Bumpl3locks; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to a bump-block such as is used upon logging wagons or cars for receiving the blow or thrust of thelogs in being loaded thereon, and more particularly to the means for effecting the adjustment of the block to and holding it at the desired adj ustment on and for removing it from the wagon or car. It will be understood from the following description and claims, reference being had to the accompanying drawings, in which Figure 1 is a perspective view of a wagonbolster and of the bump-block applied thereto, showing the improvements. Fig. 2 represents a longitudinal vertical section through the bolster and bump-block, showing a rear extension of one of the side plates of the latter in inner side elevation. Fig. 3 is an end view showing the bump-block and its adj usting devices in rear elevation, and Fig. 4 is a plan view of a portion of the bolster faceplate.

1 indicates a bolster of usual construction, such as is applicable to a wagon or car for logging purposes, provided on its upper face with a face-plate 2 of greater width than the bolster, causing its front and rear edges to project beyond said bolster.

3 indicates the bump-block, so called, having its forward or receiving face inclined to an angle of forty-five degrees, more or less, for adapting it to relieve the force of the blow of the logs being loaded upon the vehicle and provided on its sides with plates 4 4, connected with the block by means of throughbolts 5, as indicated. The lower edges of these plates 4 4 project below the block and are provided with inturned flanges underlying the projecting edges of the face-plate 2 for holding the block in engagement with said plate and permitting its lateral movement thereon relative to the vehicle. The rear ends of these plates 4 4 are extended beyond the rear end of the block and form the support for the adj usting and controlling devices of said block, as will appear. 6 6 indicate perforated lugs secured to the inner sides of each of said side plates and forming guides for the arms of the staple or U-shaped locking-bar 7, the arms of which are adapted to pass through said lugs and to engage the perforations formed in the sides of the face-plate 2. Upon the arms of the locking-bar, intermediate the upper and lower lugs 6 6, are spiral springs acting against the upper lugs and upon a lug or pin formed upon the arms of said locking bar for forcing the latter downwardly into engagement with the faceplate. Upon a through bolt or shaft 8, extending through the said plates 4: in the rear of the locking-bar, is mounted a forked lever 9, the hooked arms of the forked end of which pass under the loop of the staple or U-shaped locking-bar. The forward arms of said 1ever in advance of the pivot-bar of said lever unite in a loop and have connected with them a chain 10, extending to one side of the wagon and adapted to operate the lever for withdrawing the arms of the locking-bar from engagement with the faceplate, thereby releasing the bump-block and adapting the same to be adjusted thereon or on the bolster or to be removed by a further draft on said chain from the wagon or car at will by any suitable power applied thereto.

By the construction described it will be seen that the devices for locking the bumpblock to the bolster and for detaching the same and removing it from the bolster are simple and durable in their arrangement, not liable to get out of order, and are such as will be found effective in operation.

Having thus fully described ourinvention, what we claim as new, and desire to secure by Letters Patent, is

1. The combination with a Wagon or car bolster, of a face-plate projecting on opposite sides of said bolster, and a bump-block having side plates with pendent flanged edges engaging said plate, substantially as described.

' gaging the wagon-bolster and with rear extensions for supporting the adjusting and locking devices,and the perforated face-plate on the bolster for engaging said side plates, in combination with the staple or U-shaped bar carried by said plates and adapted to engage the bolster face-plate for locking the same at any desired adjustment, and means for adjusting said staple or U-shaped locking-plate, substantially as described.

4. A bump-block for logging-wagons,

provided with pendent flanged side plates engaging the wagon-bolster and with rear eX- tensions for supporting the adjusting and locking devices, and the perforated face-plate on the bolster for engaging said side plates, in combination with the staple or U-shaped bar carried by said plates and adapted to engage the bolster-face-plate for locking the same at any desired adjustment, and springs for forcing the arms of said locking-bar into engagement with the bolster, and a forked lever and chain for withdrawing said locking-bar and permitting the removal of the bump-block, substantially as described.

In testimony whereof We have signed this specification in the presence of two subscrib ing witnesses.
